The short answer is nobody really knows. It is my contention that on balance the presence of an anklet indicates a woman has a high libido. This would actually need a study conducted in order to answer the questions what does wearing an anklet mean.
As has been mentioned elsewhere there is some thought that women in the swinging lifestyle indicate a preference for sexual partners based on which anklet she wear’s the anklet but there is no literature or data to support this view.
